PILINQ; AND PACKING APPARATUS Application m d September as, 1927. Serial"Ne. 222,680;

This invention relates to packing and piling apparatus for packing andpiling sheets and b plates in connection with tin mill apparatus piledby hand on an annealing stand or other support in readiness for the nextoperation which generally s an annealing operation. Thepresent inventionprovides an automatic packer and piler which entirely dispenses with themanual labor hertofore used to pack and pile the'sheets and plates.

In the drawings Figure 1 is a plan view of a packer and pilerconstructed in accordance with this invention.

Figure 2 is a side elevation thereof. 1 Figure 3 is a perspectiveelevation of a modified form of stop and guide member.

Referring more particularly to the drawings, the numeral 2 designates aconveyer for delivering the sheets and plates to be packed and piled.

. The packer and piler comprises a frame 3 in which is journaled aconcave feed roller 4. A convex feed roller 5 is journaled .in a pair ofarms 5 pivotally secured to the frame 3.

A screw shaft 6 is journaled in the frame 3 and is provided with a crankhandle 7 by which it may be rotated. A pair of right and left-handthreaded nuts 8 and 9, respectively,

1 are threaded on the shaft 6 and are. supported by a rest bar or rail10. c

A pair of side bars 12 and 13 are secured to the nuts 8 and 9,respectively. Each of the bars 12 and 13 is provided with a sideguideplate 15 which is flared outwardly at its upper edge, as at 16.

A mounting disk 17 is provided with diametrically opposite screwthreaded arms 18, which arms project through apertures adj acent therear ends of the side bars 12 and 13, and are held in place by jam-nuts19.

The disk 17 is provided with a centrally disposed aperture in which athreaded bar 20 is slidably mounted." A pair of jam-nuts 21 ar .inposition in said disk.

.A combined stop and guide-plate 22 is -secured to the inner end of thebar 20 and comprises a vertical pile forming portion a,and a curvedguide portion 6. The curved guide portion b of the plate 22 is bentforwardly in the direction of travel of the sheets and plates, from theupper end of the vertical pile forming portion a, and then .curvedrearwardly and upwardly so as to extend materially rearward of thevertical plane of the 7 vertical portion a.

are provided on the bar 20 for locking said I A rearpile guide 24 issecured to the frame 3 to guide the rear end of the sheets and plates.An annealing box base 25 or other support is adapted to be located belowthe packing and piling mechanism to receive the pile of sheets orplates. In operation the sheets or plates, designated by the letter. Y,are fed into the bite of the feed rollers 4 and 5 of the packer andpiler. The rollers ,4 and 5, due to their respective concave and convexshape, will bend the sheets or plates transversely as they pass betweenthe rollers, thereby stiffening the sheets and plates so as to preventthem dipping or sagging." The rollers 4 and 5 will project the sheets orplates forwardly against the stop-plate 22 at a point adjacent its upperend and due to the novel curved shape of the stop-plate 22, the forwardend of the sheet or plate will be guided downwardly while it is stillbeing projected forward. The curve of the stop-plate 22 is suflicient topermit'the sheets or plates being piled to pass from between the rollers4 and 5, and after the sheet or plate leaves the rollers 4 and tated bymeans of the handle 7 so as to cause the nuts 8 and 9, to travel alongthe shaft 6, either toward or away from each other, as desired. i

Since the side bars 12 are secured to the nuts 8 and 9, the bars 12 andside-guides 15 will be movedwith the nuts 8 and 9. After the side-guides15 are correctly positioned the jam-nuts 19 will be tightened so as tocenter the shaft or bar 20 carrying the stop and guide-plate 22. The baror shaft 20 will then be moved forward or rearward, as desired, tocorrect position and the j am-nuts 21 tightened to lock the plate 22 inposition.

In Figure 3 we have shown a slightly modified form of stop andguide-member 22, composed of a plurality of bars or fingers 30 mountedin a base 31 and having the guideportion 6 and pile forming portion a.

While we have shown and described one embodiment of our invention itwill be understood that we do not wish to be limited thereto sincevarious modifications may be made without departing from the scope ofour invention as defined in the. appende claims.

We claim- 1. In a sheet mill apparatus, means for feeding sheets andlates out over a support, and a stop for limiting the movement of saidsheets and plates and for causing said sheets and plates to descend bygravity in an orderly manner forming a pile, said sto comprising a wallmember having a straig t vertical pile forming portion and a curvedguide portion, said curved guide portion bein bent forwardly from theupper end of sai vertical portion in the direction of travel of saidsheets and plates and then rearwardly and upwardly, said curved guideportion being adapted to engage the forward ends of the plates andsheets and direct said sheets and plates downwardly toward said support.

2. In a sheet mill apparatus, a pair of feed rollers adapted to projectsheets and plates to be piled out over a support and a stop for limitingthe movement of said sheets and plates and for causing said sheets andplates to descend by gravity in an orderly manner forming a pile on saidsupport, said stop being adjustable toward and away from said rolls,said stop comprising a wall member having a straight vertical pileforming portion and a curved guide portion, said curved guide portionbeing bent forwardly from the upper end of said vertical portion in thedirection of travel of said sheets and plates and then rearwardly andupwardly, said curved guide portion being adapted to engage the forwardends of the sheets and plates and direct said sheets and platesdownwardly toward said support.

3. In a sheet mill apparatus, a pair of feed rollers adapted to projectsheets and plates to be piled out over a support, one of said rollersbeing convex and the other of said rollers being concave whereby saidsheets and plates are curved transversely so as to stiffen them andcause them .to be projected over said support without dipping orbending, and a stop for limiting the movement of said sheets and platesand for causing said sheets and plates to descend by gravity in anorderly manner forming a pile on said support, said stop beingadjustable toward and away from said rolls, said stop comprising a wallmember having a straight vertical pile forming portion and a curvedguide portion, said curved guide portion being bent forwardly from theupper end of said vertical {portion in the direction of travel of saidsheets and plates and then rearwardl and u wardly, said curved guideportion being adapted to engage the forward ends of the plates andsheets and direct said sheets and plates downwardlgntoward said support.
